SPECIFICATION forming part of Letters Patent No. 542,193, dated July 2 1895.

Application filed March 2 3, 1895.

.T a'ZZ witam, it may conccrn:

Be it knownwthat I, WILLIAM J. HULL, a citizen of the United States, residing at Cambridge Oity, in the county of Wayne and State of Indiana, have invented new and useful Improvements in Station-Indicators, of

which the following is a specification.

' station-indicator the'ribbon-carrying rollers or drums of which cannot be turned or tampered with without causing an alarm to be made and means whereby the sounding of the alarm is continuous while the said carrying-drums are being moved and during the time which the Winding-key is applied to said drums-V I attain these objects by means of the mechanism in'the indicator illustratedin the accompanying drawings, in which similar numerals of reference designate like parts Athroughout the .several views.

'Figure 1 is afront view of the face of the indicator. Fig. 2 is a rear view of the same with the rear cover removed to exhibit the mechanism incloseditherein. Fig; 3 is an end view of the indicator-case, showing the keyhole guard or cover in its upper or normal position. Fig. 4 is a similar view showing said guard in its lower position and exposing the key-winding ends of the indicatorribbon drums. Fig. 5 is an end sectional view of the indicator. Fig. 6 is an enlarged broken detail sectional view of the gong-operating mechanism and showing the relcasing mechanism thereof. Fig. 7 is a detail view of the striking mechanism' of the gong, and Fig. 8 is a detail view of the winding-key of the ribbon-carrying drums.

The indicating-ribbon has the names of the various' stopping-stations printed in large clear type on its face in the regular order of succession and is rolled on and carried by the ribbon-carrying drums 2 and 3 with its printed surface or face turned toward the longitudinal slot Orppening 4:, formed in the front Serial No. 542,918. (Nomodel.)

of the inclosing-case 5 of theindicator. The dru'ms 2 and 3 are each journaled at their ends in suitable bearings secured to the ends of the case 5. One of the ends of each of the journals of the ribbon-carrying drums is prolonged beyond its journal-bearing and is flush with the outer surface of the end of the case 5, and each .of these prolonged ends of the journal are formed square for a portion ofy their length to form key-iits 6, whereon the winding-key 7 of the drums is applied.

The gong 8 is sounded or operated byA means of a suitable clockwork driven by a clock-spring in the usual well-known manner, and is provided With la striking-hammer 9, which is actuated by au escapement-wheel 10, all of which mechanism being carried by the same separable frame 11 and inclosed by the gong 8.

Any suitable gong actuated by clockwork or other means, as electricity, may be used in connection with my station-indicators, as such does not form a part of my invention.

The striking-hammer 9 is held or engaged to prevent its striking the gong 8 by the collar 12 on the staff 13, and said collar 12 is held in contact with said hammer 9 by the coilspring 14. To release the hammer 9 to permit it to strike the gong 8, the staff 13 is moved longitudinally to disengage the collar 12 from said hammer, which movements further compress the coil-spring 14, which latter moves the said sta into its normal position when the shaft is released.

The spring-cam 15 is secured at its end to the inner surface of the casing 5, and has its free end projecting or lapping over the end of the staff 13. The enunciating-lever 16 is fulcrumed at a point intermediate between its ends, and is provided with the coil-spring 17, secured in any suitable manner to the casing 5 and bearing against the end of the lever 16, and by which said lever is moved and held in its normal position, as shown in full lines in Fig. 2. The inner or free end of the lever 16 extends or laps over the spring-cam 15, below the bend thereof, in such a manner that when the arm of the said lever 16 is moved in the position shown in dotted lines (see Fig. 2 and detail Fig. 6) thespring-cam 15 will be compressed to push the staff 13 in the direction of the arrow and thereby release KCO the collar 12 from the hannner 9. The outer reduced end 18 of the level` 16 pt'ojeets through a notch or slot 19, fot'tned in the key guard-plate 20.

The key gnard-plate 20 is formed of a fiat metallic material, pi'eferably of sheet brass, and has the lower bend or finger-catch 21` formed thereon, and is provided with the guideslots 22, adapted to receive the guiding-pins 23, which are secux'ed in the casing 5, and by which said guard-plate is held on said casing 5 to slide vertically thereon.

The slots 22 of the guard-plate 20 are of a snffieient length to perinit the downward movement of said guard-plate to cause the key-openings 24 to fall opposite or' registeri with the key-openings 25, formed in the end; of the case 5, and in these o penings'the'wind-i` ing-key is inserted and applied ont-hesquat'e i, ot' key ends of `the joni'nals of thei'ibbon-'carf l'ying dx'nins when the said gnard -plate is movetl into the position shown in Fig. 4. w

The names of the variousstopping-stations of a railway ot' branch ther'eof are printedton f one side of ``the ribbon in their regulai' o1'der} of i'otation along' the line of travel, and when a train has eitherle'ft astationtoi' is approachinganotheror the'nextconseentiv'e station,an-1 officialtprovided with the proper key,as shown i in Fig. 8, pulls the guardeplate 20 into-the position shown ion Fig. 4, thns nncovel'ing thef key-fits of the tape'oarrying drums, which he tnrns till the next consecutive name of the stopping-station is exhibited through the slot or opening 4. The downward movement of the guard-plate 20 rotates the level' 16, the inner end of which compresses the cam-spring 15, thns moving thestaif 13, and, disengaging the hammer 9 of the gong 8, allows the alarm to sound, hwhich alarm oontinues while the guard-plate 20 is held in its lowet` position.

Having thus fully described the construction, use, and operation' of my invention, what I claim as new and useful, and desil'e to eoverlby Letters Patent of the United States therefor, is-

In astation ind'icator, the combination with 'an inclosing oasing, upper and lowei` key winrlingdt'ums and an'indicatot' ribbon, of an alarm nleehanisrn on said casing, a gnax'd -ovei' the key winding' ends of said drnms, a cam spring, a level' having one end lappingr over said nam 'spring anditsopposite end en- ;zaging said key guard plate, snbstantially as and fot' the pui'pose set forth.

In testimony whereof I lhave hereunto set 'my hand in thepi'esenceof two subsci'ibing witnesses.
